What are the signs of a dishwasher going out?


Editorial team Published on

Common signs your dishwasher is failing include dirty dishes after a full cycle, standing water at the bottom, and strange grinding or burning noises.

Key Signs of Failure

  • Dirty or Spotty Dishes: Food residue remaining after a cycle often points to a clogged filter, blocked spray arms, or a failing circulation pump.
  • Standing Water: A pool of water left at the bottom of the tub after a cycle finishes usually indicates a blocked drain hose, a clogged filter, or a broken drain pump.
  • Unusual Noises: Loud grinding, buzzing, or rattling sounds suggest debris in the pump or worn-out motor bearings.
  • Water Leaks and Rust: Puddles on the floor or rust flakes inside the tub mean door gaskets, seals, or the tub itself have cracked or worn out.
  • Cold Dishes: If dishes are cold or wet post-cycle, the heating element may be broken and unable to sanitize or dry properly.
  • Burning Smell or Tripping Breakers: A burning odor or a unit that constantly trips the circuit breaker indicates an overheating or shorting pump motor.
  • Old Age: Most dishwashers last 10 years; units older than this with recurring problems should generally be replaced rather than repaired.
